Abstract
We define nuclear halos states and derive and discuss occurrence conditions leading to constraints on neutron N and proton Z numbers, the total nuclea r excitation energy E* and the binding energy B of the halo state. Only ext remely small values of E* allow halo formation, which also requires small B . Low N and Z seems to be favored. We give upper limits for B for E* = 0. ( C) 2000 Elsevier Science B.V.
